Technical Field
The utility model relates to an environmental test cabin field, specifically speaking, in particular to jacket formula environmental test cabin.
Background
The environmental test chamber is a device for testing the VOC (volatile organic compounds) release amount of formaldehyde. The sample in the chamber releases pollutants into the air in the chamber under certain conditions, and the environmental protection level of the sample is judged by measuring the concentration of the pollutants in the air in the chamber. The temperature of the existing formaldehyde VOC release amount test environmental chamber is controlled by adopting a built-in heat exchanger (internal circulating water), and the control mode has the defects that:
1. the temperature control speed is slow, the temperature needs to be indirectly adjusted by changing the water temperature, and the temperature adjusting efficiency is low.
2. The temperature controllable range is narrow, and the temperature range is limited only to be 0-100 ℃ by the characteristics of water.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a jacket formula environmental test cabin to the not enough among the prior art to solve the problem that exists among the prior art.
The utility model provides a technical problem can adopt following technical scheme to realize:
a jacket type environmental test chamber comprises a test chamber main body, wherein the inner space of the test chamber main body is divided into a working chamber for placing a sample to be detected and an equipment chamber for installing a temperature control component;
a heat insulation material layer is arranged on the inner wall of the test cabin main body outside the working cabin, the heat insulation material layer and the outer wall of the working cabin form a circulating air duct, and the circulating air duct is communicated with the equipment cabin through an air outlet and an air inlet; the temperature control assembly comprises a fan and a temperature adjusting device, the temperature adjusting device is connected with the air outlet through an air inlet pipe, the temperature adjusting device is connected with the air inlet through an air outlet pipe, and the fan is arranged on the air inlet pipe or the air outlet pipe.
Further, the temperature adjusting device comprises a shell, and a semiconductor refrigerator and a ceramic heating plate which are arranged in the shell, wherein the semiconductor refrigerator is used for reducing the temperature of air flowing through the temperature adjusting device, and the ceramic heating plate is used for increasing the temperature of the air flowing through the temperature adjusting device.
Furthermore, the air outlet and the air inlet are arranged on one side of the circulating air duct close to the equipment cabin.
Furthermore, a plurality of universal wheels are arranged at the bottom of the test chamber main body.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. the temperature is adjusted by adopting air with smaller specific heat, and the temperature adjusting efficiency is high.
2. The temperature controllable range is wide and is not limited to 0-100 ℃.
